From now on, we offer a suiting water cooling set for all owners of the ASUS RAMPAGE V EXTREME. The HEATKILLER® MB-X KIT enables remarkable temperature decreases in both VRMs and chip set, and hence improves overclocking potential. The realm of possibilities in water cooling thus becomes much enlarged.

You should consider using the kit also if you are not into overclocking. Lower temperatures prolong the components' service life and like this make your hardware investments more sustainable.

The coolers' bottom plates are manufactured from electrolytic copper. Depending on the precise version, the copper becomes nickel-plated after that. The top is made from black POM.

The VRM cooler is solely available, too.
